FLY-SCREEN.

SPECIFICATION forming part of Letters Patent N o, 563,314,`dated uly '7,18,96.

Application filed April lo, 1896.

.To @ZZ whom it may concern.'

Bc it known that I, THOMAS H. ScHUErz, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Fly- Screens, of which the followin gis afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention has relation to improvements in ily-screens; and itconsists in the novel arrangement andcombination of parts more fully setforth in thespecilication and pointed out in the claims.

In the drawings, Figure l is an elevation of a screen-door viewed fromthe inside'of the room to which it leads. Fig. 2 is a vertical sectionon .fr 0c of Fig. l. Fig. 3 is a similar section of a portion of thedoor with the screen removed. Fig. 4- is a detail showing the blockwhich retains in place the deflected portion of the screen orwire-netting, and Fig. 5 is an inside elevation of the parts shown inFig. 3.

The'object of my invention is to construct a ily-screen for doors,windows, and the like which, when the door or window screen is closed,permits any stray iiies in the room that might land or mount on thescreen to find their Way along the screen or web out into the openwithout danger of thellies returning into the room through the openingfrom which the insects emerged or found their way out. In detail thedevice may be describedvas follows:

Referring to the drawings, l l represent the side members of the frameof a door-screen, ornamented with suitable scrollwork 2 2, the said sidemembers being connected along the length thereof by a series of crosspieces or members 3 and 3 flush with what corresponds to the outsidesurface of the door when hung.

4 represents the terminal bars or members of the frame. 5 represents aseries of sheets of wire netting or webs extending across the width ofthe opening of the frame, and lapping a suitable distance beyond theline of the inner edges of the side members to which the sides of thescreens are securely fastened and covered by suitable beading 6. In thepresent instance, the lower web 5 is secured serial Np. 587,801.(Np'mpiel.)

i able triangular cut-away portions or notches formed along the innerlateral faces of the side members l. The depth of each triangular-notchthus cut extends to the 'rear surface of thev cross pieces or members 3,to which rear surface the upper edge of the deflected portion 5' of theweb is'secllred by beading 8.

To retain the deflected portion of the web firmly against t-he basalledge 7 of the notch, suitable triangular blocks 9 are superposed overthe edges of the web resting on the ledges 7 and nailed to the sides ofthe cut-away portions, the dimensions of each block being such that theyaccurately fit the cut-away portion, and come flush with the innersurface of the members '1.

In the present construction of the screendoor the straight edge of eachblock has cut therein a suitable notch or miter lO, in which rest theopposite ends of the inner cross-pieces ll, to which the basal or loweredge of each successive screen is secured and covered by suitablebeading lo". The pieces ll break joint with the pieces 3, beingrelatively located below the latter when the door is hung. The upperedge of the uppermost web is of course secured directly to the uppertransverse member 4. By the present construction, when the door isproperly hung, a suitable space is left between the deiiected portion 5and the lower end of each succeeding web, and when a fly alights on oneof the webs 5 on the inside of the door, the insect (whose tendency isto always walk up) will pass into theV space formed between theoverlapping ends of any two successive screens or webs and find its wayto the outside of the frame, when the probabilities are that it will notreturn by the same route along which it emerged. The arrows indicate thedirection the fly takes from the inside to the outside of the frame.

It is obvious that the frame as a whole IOO might be altered inmechanical details Without in any wise afecting the spirit of myinvention.

16 represents beading disposed transversely and covering portions of thescreens not otherwise previously referred to.

Having described my invention, what I claim is l. In a ily-screen, asuitable frame having side members, suitable cut away portions formedalong the inner faces of the side members, cross-pieces disposed alongthe outside surface of the frame, the maximum depth of the cut-awayportions being such as to lead or extend to the rear surface of thecross-pieces, a screen having a deflected portion and having its sidesdisposed along the basal ledges of the cut-away portions, means forretaining the deflected portions of the screen against the basal ledges,and means carried by or forming a part of the frame for retaining thebase of the next succeeding screen, substantially as set forth.

2. In a fly-screen, a suitable frame having side members, suitablecutaway portions formed along the inner faces of' the side members,cross-pieces disposed along the outside surface of the frame, themaximum depth of the cut-away portions being such as to lead or extendto the rear surface of said cross-pieces, a screen having a deflectedportion and having its sides disposed along Jthe basal ledges of thecut-away portions, suitable blocks inserted into said cut-away portionsand adapted to retain the deflected portions of the.
